vPatented Oct. 11,' l1932 UNITED STATES ARNOLD I'. WEISS, Ol' IIUIBOLDT, IOWA POWIm POSTHOLE AUGEL Application led April 20,

'20 wagon or other vehicle and powered by an'.

electric notor orga'soline engine or the like. A further object is toprovide a power posthole a'ger which may conveniently be mounted on atractor or other'vehicle in such manner that it 'can be adjusted as toinclination with respect to the vehicle, there being provided a'conveniently operable' means lfor affecting and retainingsuclradjnstment. i A further object is to provide convenientlyvaccessible clutch means to control the operation of the auger and tofurther provide a feed lever for feeding the auger into the -I ground,the feed lever being arranged to "4 engage the clutch means fordisengaging it and thereby stopping rotation of the auger l whenever theauger is moved by the feed lever` to raised position. Still a furtherobject is to provide expension controls for the auger vso that it can beoperated from the driving platform of the tractor.

With these and other objects in view my invention consists in theconstruction, ar-

d rangement and combination of the various parts of my'device, wherebythe objects contemplated are attained, as hereinafter -more fully setforth, pointed out in my claims, and illustrated in the accompanyingdrawings, in which:

F igure l2 is a plan view showing it mounted on a wagon. l

0n the accompanyingff'drawings, I have used the reference character A toindicate generally a tractor. My power post hole auger includes suitableframework mounted on the-tractor which, as show n on the drawings,consists of a mounting rod 10 extended through draw bar ears 12 of thetractor and S connected with uprights 14. Tubular spacers .'16 and bracebars 18, if desired, constitute further mechanism of theframework. Theuprights 14 are connectedvwith side frames 20 which extend rearwardlyand may be connected with -any suitablepart of the tractor. Supported onthe sidefiames 20 is a plank or the like 22 having bearings 24 extendingupwardly therefrom. A drive shaft 26 is j ouriialled in the bearings2,4. A drive ulley 28 is secured to the `drive shaft 26. oll'ars 30prevent 'longitudinal movement, of the shaft 26 relative to the bearings24.

By means of a belt 32 the drive pulley 28 95 is operatively connectedwith a power pulley 34 of the tractor. An idler pulley '361s carried byan arm 38, which is Vivoted to one of the side frames 2'0. The id erpulley 36 engages the belt 32'and is actuated by a spring ,00 to causethe idler pulley to act as a belt an angle bearing 42 (see Figure 4).A'sleeve 44 is rotatable and slidable through the bear-v ing 42 and hasa bevel gear 46 rotatable thereon. A bevel pinion 48 meshesl with thebevel gear 46 and -is o ratively connected with the drive shaft 26 orthe like.

o Clutch lugs 52 are formed on the bevel gear 46 with w 'ch clutch lu s54 on the upper end of the sle ve 44 are adapted to coact when thesleeve is in a lowered position. The inside of the sleeve 44 is eitherangular or isprovided with a key and an auger shaft 56' extendstherethrough and is sli-dable, but non-rotatable relative thereto. Thelower end of the auger shaft 56 is screw-threaded, as indicated at 58and any vdesired type of auger 6() may .l be secured thereto. By meansof the screwthe clutch lugs 52 and 54. They may be re- Fi re 2. Fidi' imartin lon itudinal movement to P g g threaded connection at 58, oneauger may be substituted for another, if desired. For engaging andseparating the clutch lugs 5.2 and 54, I provide a clutch lever 62 whichhas pivoted therein, by pins 64, a collar 66. The collar 66`engag'es anlannular flange 68 on the lower end of the sleeve 44. Gravity actingupon the clutch lever 62 will normally engage tained indisengaged-position by a latch 70, which normally engages over astationary lug 1 extending from the bearing 42, as shown in the augershaft 56 for thereby feeding the auger into the ground, I provide a feedlever `72. The feed lever 72-is slidable through a` block 74 (see Figure5) which is pivoted by a bolt 76 to a brace bar 78.

TheV feed lever 72 carries a bearing cage 79, which is pivoted on screws80. The bearing cage surrounds an annular row of ball bearings 82, whichseated ony a hub- 84. The huh 84 is securet` by a set screw 86, whemy itcan be adjusted to any position thereon desired. It will be obviousthatup and down movement of the feed lever 72 will cause up and downmovement of the auger shaft 56, the slidingconnection between the-feedlever and the block 74 permitting pivotal'movement with respectdependingonconstrluctional details of the mounting. l

tothe bolt 76 without binding. v

The feed lever 72 is provided with alug 88 adapted to engage the clutchlever 62 and means of a latch 90, which engages a lug on the bearing/42,as shown by dotted lines fin Figure 2,- the auger caribe retained inraised position.

T he angle bearing 42 permits changing the inclination of the augershaft about the drive shaft26 as a pivot. An inclination adjusting lever92 is provided which hasa bearing construction similar to that shown inFigures y a break pin of wood the auger shaft 56v f6 and 7 except thatthe h ub 84 is not secured to the auger shaft, but is slidable thereon.The lever 92 is slidable with respect to the toothed bar 96.

Brackets 98 I (see Figure 8) connected with the bars178, 94 .and 96,provide guideways `.for the sliding bar 92. The sliding bar 92 hassecured thereto an upstanding tubular extension 100 in which is housed aspring pressed ball` 102. The 'ball 102engages the teeth on the upperedge of the toothed bar 96, whereby to retain the sliding bar. 92 in lany position to whichit is adjusted.

As shown in Figure 10, the feed lever 72 may havean extension 7 2asecuredto the rear end thereof for extending the controls of the powerpost hole auger to'the driving platform of the tractor A. Alatch 90a maycoa'ct with a lug 91 forretaining the auger in raised position.` Theextension lever72a, the feed `lever 72 and the clutch lever 62 each havea small wire loop 93 whereby the latch 90a may be rendered ineilective'when operating the auger from'the frontof-the tractor'or the latchesand 90 may be rendered ineffective when operatingV the auger from thedriving platformof the tractor.

The sliding lever 92, for adjusting the inclination of the auger, can becontrolled by a pivoted lever 92a anda link 95.

In Figure 11, I have shownv the supportu.

ing plank 27 mounteld on the rear end of a tractor and suitably -lbracedby a brace 104.

Thus it will be seen that my device may be located anywhere 'on thetractor and can still be operated from the power plant of the tractor bybelt or other suitable transmission. In Figure 12, I have shownthevsupport 27 mounted on beams106, which are secured to the bed 108 of'awagon.

An engine is indicated at 110 mounted also on the bed of a wagon andoperatively connected with the auger mechanism. In either of the threetypes of mountings shown, the

auger can be .suitably inclined inasmuch as the bevel gear connectionsare provided. EachA installation can be'providedv with simi- .larcontrols which could be slightly modified,

Other changes .-may also be madein f construction and arrangement of thepartsof my device without departing from-thereal spirit and purpose ofmy invention, andit is my intention to cover by my claims,"any modifiedforms of structure or use of mechanical equivalent-s, which maybe'reasonably includdrive `means rotatable on, saidsleeve, said meansand said sleeve having lugs to coact. With each other when the sleeve isslid to a. predetermined position, a clutch lever for sliding saidsleeve, a feed lever for imparting longitudinal movement to said augershaft and means on said feed lever to engage said clutch lever and moveit to disengaged position when the feed lever assumes a predeterminedposition.
